11/15 because 3/5 converts to 9/15 so 9/15+2/15=11/15
STEP 1:
Calculate total amount of ribbon
= 2 spools * 24 yards each
= 48 yards total
STEP 2:
Divide total yards (48 yards) by portion size (1/8 yard)
= 48 ÷ 1/8
to divide fractions, we multiply by the reciprocal/inverse of 1/8
= 48 * 8/1
= 48 * 8
= 384 bows

<span>A rabbit’s heart rate should be 120-150 beats per minute so you just multiply 120 by 60 and 150 by 60 and the numbers in between that should be the amount of times a rabbit hearts beats in one hour. 60 x 120 = 7,200 and 60 x 150 = 9,000. A rabbit's heart beats between 7,200 and 9,000 times an hour. </span>
